Ground power unit load bank EAL-28

The EAL-28 is a portable 28V DC load bank from ElectroAir’s trusted EAL series, engineered to test, calibrate, and maintain Ground Power Units (GPUs) in both workshop and field environments. Designed with aerospace-grade reliability in mind, this compact and lightweight device ensures safe and accurate diagnostics of 28.5V power supply systems without the need to connect to actual aircraft. Using the EAL-28, technicians can simulate engine start loads and perform comprehensive performance checks on GPUs before deployment. This allows MRO teams and airport maintenance crews to detect and correct issues early, reducing downtime and preventing potential malfunctions during real operations. The load bank operates as a fully independent unit, requiring no auxiliary systems. Its portable design and easy-to-use interface make it an ideal tool for regular maintenance, troubleshooting, and certification procedures. Compatible not only with ElectroAir units but also with most third-party GPU systems, the EAL-28 brings versatility and peace of mind. Its high thermal tolerance and precision components ensure stable performance even under prolonged use. With growing industry demands for accuracy and operational readiness, the EAL-28 delivers the confidence technicians need to guarantee uninterrupted aircraft servicing and compliance with aviation standards.
